| 1 | Secondary causes of inflammatory bowel diseases显示文摘Inflammatory bowel diseases(IBD),conventionally consist of Crohn’s disease(CD)and ulcerative colitis.They occur in individuals with high risk genotype for the disease in the setting of appropriate environmental factors.The pathogenesis of IBD involves a dysregulated autoimmune response to gut dysbiosis,which in turn is triggered due to exposure to various inciting environmental factors.But there is no clearly defined etiology of IBD and this type of disease is termed as“idiopathic IBD”,“classic IBD”,or“primary IBD”.We reviewed the current medical literature and found that certain etiological factors may be responsible for the development of IBD or IBD-like conditions,and we consider this form of de novo IBD as“secondary IBD”.Currently known factors that are potentially responsible for giving rise to secondary IBD are medications;bowel altering surgeries and transplantation of organs,stem cells or fecal microbiome.Medications associated with the development of secondary IBD include;immunomodulators,anti-tumor necrosis factor alpha agents,anti-interleukin agents,interferons,immune stimulating agents and checkpoint inhibitors.Colectomy can in some cases give rise to de novo CD,pouchitis of the ileal pouch,or postcolectomy enteritis syndrome.After solid organ transplantation or hematopoietic stem cell transplantation,the recipient may develop de novo IBD or IBD flare.Fecal microbiota transplantation has been widely used to treat patients suffering from recurrent Clostridium difficile infection but can also causes IBD flares. | Yezaz A Ghouri Veysel Tahan Bo Shen | 2020 | World Journal of Gastroenterology2020，26，28： | 13 |
| 2 | N-acetylcysteine attenuates alcohol-induced oxidative stess in rats显示文摘AIM: To investigate free-radical scavenger effect of nacetylcysteine in rats intragastrically fed with ethanol.METHODS: Twenty-four rats divided into three groups were fed with ethanol (6 g/kg/day, Group 1), ethanol and nacetylcysteine (1 g/kg, Group 2), or isocaloric dextrose (control group, Group 3) for 4 weeks. Then animals were sacrificed under ether anesthesia, and intracardiac blood and liver tissues were obtained. Measurements were made in both serum and homogenized liver tissues.Malondialdehyde (MDA) level was measured by TBARS method. Glutathione peroxidase (GSH-Px) and superoxide dismutase (SOD) levels were studied by commercial kits.Kruskal-Wallis test was used for statistical analysis.RESULTS: ALT and AST in Group 1 (154 U/L and 302 U/L,respectively) were higher than those in Group 2 (94 U/L and 155 U/L) and Group 3 (99 U/L and 168 U/L) (P=0.001for both). Serum and tissue levels of MDA in Group 1 (1.84nmol/mL and 96 nmol/100 mg-protein) were higher than that in Group 2 (0.91 nmol/mL and 64 nmol/100 mg protein)and Group 3 (0.94 nmol/mL and 49 nmol/100 mg-protein)(P<0.001 for both). On the other hand, serum GSH-Px level in Group 1 (8.21 U/g Hb) was lower than that in Group 2(16 U/g Hb) and Group 3 (16 U/g-Hb) (P<0.001). Serum and liver tissue levels of SOD in Group 1 (11 U/mL and 26U/100 mg-protein) were lower than that in Group 2 (18 U/mL and 60 U/100 mg protein) and Group 3 (20 U/mL and 60 U/100 mg-protein) (P<0.001 for both).CONCLUSION: Ethanol-induced liver damage was associated with oxidative stress, and co-administration of n-acetylcysteine attenuates this damage effectively in rat model. | Resat Ozaras Veysel Tahan Seval Aydin Hafize Uzun Safiye Kaya Hakan Senturk | 2003 | World Journal of Gastroenterology2003，9，4： | 9 |
| 3 | Fatty liver without a large“belly”:Magnified review of nonalcoholic fatty liver disease in non-obese patients显示文摘Nonalcoholic fatty liver disease(NAFLD) is well described as a common cause of chronic liver disease, mostly in the obese population. It refers to a spectrum of chronic liver disease that starts with simple steatosis than progresses to nonalcoholic steatohepatitis and cirrhosis in patients without significant alcohol consumption. NAFLD in the non-obese population has been increasingly reported and studied recently. The pathogenesis of nonobese NAFLD is poorly understood and is related to genetic predisposition, most notably patatin-like phospholipase domain-containing 33 G allele polymorphism that leads to intrahepatic triglyceride accumulation and insulin resistance. Nonobese NAFLD is associated with components of metabolic syndrome and, especially, visceral obesity which seems to be an important etiological factor in this group. Dietary factors and, specifically, a high fructose diet seem to play a role. Cardiovascular events remain the main cause of mortality and morbidity in NAFLD, including in the nonobese population. There is not enough data regarding treatment in non-obese NAFLD patients, but similar to NAFLD in obese subjects, lifestyle changes that include dietary modification, physical activity, and weight loss remain the mainstay of treatment. | Mohamad H Yousef Alhareth Al Juboori Abdulmajeed A Albarrak Jamal A Ibdah Veysel Tahan | 2017 | World Journal of Gastrointestinal Pathophysiology2017，8，3： | 9 |
| 4 | Interventions to improve sarcopenia in cirrhosis: A systematic review显示文摘BACKGROUND Sarcopenia, i.e., muscle loss is now a well-recognized complication of cirrhosis and in cases of non-alcoholic fatty liver disease can contribute to accelerate liver fibrosis leading to cirrhosis. Hence, it is imperative to study interventions which targets to improve sarcopenia in cirrhosis.AIM To examine the relationship between interventions such nutritional supplementation, exercise, combined life style intervention, testosterone replacement and trans jugular intrahepatic portosystemic shunt(TIPS) to improve muscle mass in cirrhosis.METHODS We search PubMed, EMBASE and Cochrane between June-August 2018, without a limiting period and the types of articles(RCTs, clinical trial, comparative study)in adult patients with sarcopenia and cirrhosis. The primary outcome of interest was improvement in muscle mass, strength and physical function interventions mentioned above. In the screening process, 154 full text articles were included in the review and 129 studies were excluded.RESULTS We identified 24 studies that met review inclusion criteria. The studies were diverse in terms of the design, setting, interventions, and outcome measurements.We performed only qualitative synthesis of evidence due to heterogeneity amongst studies. Risk of bias was medium in most of the included studies and low quality of evidence showed improvement in the muscle mass, strength and physical function following aerobic exercise. 60% of the included studies on the nutritional intervention, 100% of the studies on testosterone replacement in hypogonadal men and trans-jugular portosystemic shunt were proved to be effective in improving sarcopenia in cirrhosis.CONCLUSION Although the quality of evidence is low, the findings of our systematic review suggest improvement in the sarcopenia in cirrhosis with exercise, nutritional interventions, hormonal and TIPS interventions. High quality randomized controlled trials needed to further strengthen these findings. | Maliha Naseer Erica P Turse Ali Syed Francis E Dailey Mallak Zatreh Veysel Tahan | 2019 | World Journal of Clinical Cases2019，7，2： | 8 |

| 6 | Epidemiology,determinants,and management of AIDS cholangiopathy:A review显示文摘Diseases of the liver and biliary tree have been described with significant frequency among patients with human immunodeficiency virus(HIV), and its advanced state, acquired immunodeficiency syndrome(AIDS). Through a variety of mechanisms, HIV/AIDS has been shown to affect the hepatic parenchyma and biliary tree, leading to liver inflammation and biliary strictures. One of the potential hepatobiliary complications of this viral infection is AIDS cholangiopathy, a syndrome of biliary obstruction and liver damage due to infection-related strictures of the biliary tract. AIDS cholangiopathy is highly associated with opportunistic infections and advanced immunosuppression in AIDS patients, and due to the increased availability of highly active antiretroviral therapy, is now primarily seen in instances of poor access to antiretroviral therapy and medication non-compliance. While current published literature describes well the clinical, biochemical, and endoscopic management of AIDS-related cholangiopathy, information on its epidemiology, natural history, and pathology are not as well defined. The objective of this review is to summarize the available literature on AIDS cholangiopathy, emphasizing its epidemiology, course of disease, and determinants, while also revealing an updated approach for its evaluation and management. | Maliha Naseer Francis E Dailey Alhareth Al Juboori Sami Samiullah Veysel Tahan | 2018 | World Journal of Gastroenterology2018，24，7： | 5 |
| 7 | Kinetic study on leaching of nickel from Turkish lateritic ore in nitric acid solution显示文摘Dissolution kinetics of nickel from lateritic ore in nitric acid solution was investigated. Experimental parameters used were stirring speed(100-600 r/min), temperature(40-96 °C), nitric acid concentration(0.1-2 mol/L) and particle size(<106 μm). The shrinking core model was applied to the results of experiments investigating the effects of leaching temperature in the range of 40-90 °C and nitric acid concentration in range of 0.1-2 mol/L on nickel dissolution rate. The kinetic analysis shows that the nickel dissolution from lateritic ore could be described by diffusion model. The activation energy(E_a) for the dissolution reaction is calculated as 79.52 kJ/mol. | Tevfik AGACAYAK Veysel ZEDEF Ali ARAS | 2016 | Journal of Central South University2016，23，1： | 4 |

| 9 | Malformations of cortical development:3T magnetic resonance imaging features显示文摘Malformation of cortical development(MCD) is a term representing an inhomogeneous group of central nervous system abnormalities, referring particularly to embriyological aspect as a consequence of any of the three developmental stages, i.e., cell proliferation, cell migration and cortical organization. These include cotical dysgenesis, microcephaly, polymicrogyria, schizencephaly, lissencephaly, hemimegalencephaly, heterotopia and focal cortical dysplasia. Since magnetic resonance imaging is the modality of choice that best identifies the structural anomalies of the brain cortex, we aimed to provide a mini review of MCD by using 3T magnetic resonance scanner images. | Bilal Battal Selami Ince Veysel Akgun Murat Kocaoglu Emrah Ozcan Mustafa Tasar | 2015 | World Journal of Radiology2015，7，10： | 2 |
